Abstract: A submerged nozzle has a lower part with a bottom and two outlet side channels above the bottom, and a skirt with a center fixed to the lower part of the nozzle above the outlet side channels. The skirt has two parallel flat surfaces each having side edges that are smoothly connected to each other by two respective cylindrical surfaces, the two outlet side channels being identical and lying along a common longitudinal axis making an acute angle with the parallel flat surfaces. A portion of the skirt is spaced apart from the nozzle to allow hot metal to flow in the space between the nozzle and the skirt.

Abstract: The invention relates to the iron and steel industry, more specifically, to continuous slab casting using a submerged nozzle. The inventive submerged nozzle comprises a bottom, lateral channels and a skirt which is secured to the lower part of the nozzle above the output lateral channels and is formed by two parallel flat surfaces which are gradually conjugated on the ends thereof by means of cylindrical surfaces. The nozzle is arranged in the center of the skirt and has two similar oppositely positioned lateral channels having a common longitudinal axis which forms together with the parallel flat surfaces of the skirt an acute angle ranging from 20 to 45°.
